delete seemingly unused deps

Summary:
Delete some crosvm dependencies that appear to be unused (maybe leftover from a
previous attempt at buckification?)

The previous diff fully buckifies `crosvm` in `third-party/crosvm`, so this
diff removes traces of it left elsewhere.

If any other code in fbcode needs to depend on these targets in the future,
they should just depend directly on the targets in
`fbsource//third-party/crosvm:` instead of forcing a separate copy to be kept
in `fbsource/third-party/rust` which can easily diverge from the copy used to
build the main `crosvm` binary kept in `fbsource/third-party/crosvm`
